denim patchwork skirt

[jesamine.livejournal.com]

right, i had a load of bits of denim left over from when i made 2 jeans bags. i was going to make shorts, but decided i want a skirt instead.
i've started tacking the squares together in lines so far. i'm not actually sure i'm going to have enough denim now, but i can always cut up another pair of jeans, heh...
anyway, does anyone know how to make a skirt? heh! i have an idea...but i know i'll get stuck on how to do the waistband...

can anyone help? thanks :)
